Explanation:
The working directory is just a file path on your computer that sets the default location of any files you read. If you want to read a file 'file.txt'.
After you use the create sequence statement to create a sequence, you can use the NEXTVAL pseudo column to get the next value in the sequence.
<h3 /><h3>How do you create a sequence?</h3>
- You must have the Create any sequence system privilege to create a sequence in another user's schema.
- Specify the schema that will hold the sequence.
- If you leave out schema, Oracle Database will create the sequence in your own schema. Name the sequence that will be created.
- Pseudo-columns allow selection, but you cannot edit, update, or remove their values.
- A pseudo-column is analogous to a function that does not accept any inputs. This section goes over the two pseudo-columns, CURRVAL and NEXTVAL.
- A pseudo column is a "column" that displays a value when a value is selected but is not one of the table's true columns.
- Two examples are SysDate and RowID. It is frequently used in tandem with the DUAL table.
- After you utilize the make sequence statement to make a sequence, you can utilize the NEXTVAL pseudo column to obtain the next value in the sequence.

Based on computing network operation, it is <u>false</u> that VLANs in cloud computing are most likely to be found on direct connections with a CSP.
<h3>What is VLAN?</h3>
VLAN is an acronym of Virtual Local Area Network that establishes its broadcast domain which enables network admins to combine hosts regardless the hosts are connected on the same network switch or not.
Given that the VLAN created its broadcast domain, you are likely not found it on direct connections with a CSP.
Hence, in this case, it is concluded that the correct answer is False.
